Packers fans, along with Joe Buck and Troy Aikman, are to get a sneak peak of San Francisco 49ers, the Packers’ first regular-season opponent on Sept. 9.

On Sunday at 3 p.m. Buck and Aikman are to call the 49ers at Denver Broncos pre-season telecast on Fox. They also will handle 49ers-Packers in Week 1’s national telecast on Fox.

"Fox NFL Sunday" co-hosts Curt Menefee and Terry Bradshaw will be handling pre-game, halftime and post-game coverage of 49ers-Broncos, with Bradshaw joining Buck and Aikman in the booth during the game.

Erin Andrews, who has joined Fox, will join Menefee and Bradshaw at halftime.

Meanwhile, Fox’s NFL rules expert, Mike Pereira was interviewed by ESPN Radio and said the gap between the level of officiating by regular NFL refs and their replacements is bigger than he thought.

The NFL officials have been locked out by the league and replacements have been handling pre-season games.

"Having been to games to see it in Atlanta and Baltimore, I recognized how the difference in the rules and the interpretation of the rules affects what is called by the officials on the field," Pereira said. "The regular NFL officials have studied the rulebook for so long and have been involved in the NFL game for so long that the interpretation of the rules, penalty enforcement, and management of the clock all come naturally to them. We never have to question that. Within the area of judgment, that’s where the controversy lies even with the regular guys."
